CefSharp custom SchemeHandler

由 天大地大妈咪最大 提交于 2019-11-30 07:50:32
Iam using CefSharp's SchemeHandler in order to grab resources from my C# project like .css , .js or .png files using a custom url for example custom://cefsharp/assets/css/style.css I've 2 custom classes in order to archive this. First class, MyCustomSchemeHandlerFactory will be the one that handles the custom Scheme and it looks like this, where "custom" will be the custom scheme: internal class MyCustomSchemeHandlerFactory : ISchemeHandlerFactory { public const string SchemeName = "custom"; public IResourceHandler Create(IBrowser browser, IFrame frame, string schemeName, IRequest request) {

Using CefSharp.Offscreen to retrieve a web page that requires Javascript to render

I have what is hopefully a simple task, but it's going to take someone that's versed in CefSharp to solve it. I have an url that I want to retrieve the HTML from. The problem is this particular url doesn't actually distribute the page on a GET. Instead, it pushes a mound of Javascript to the browser, which then executes and produces the actual rendered page. This means that the usual approaches involving HttpWebRequest and HttpWebResponse aren't going to work. I've looked at a number of different "headless" options, and the one that I think best meets my needs for a number of reasons is

【Cef编译】 CefSharp编译失败，检测到“RuntimeLibrary”的不匹配项: 值“MT_StaticRelease”不匹配值“MD_DynamicRelease”

编译CefSharp生成后一个libcef_dll_wrapper.lib时，供CefSharp使用。结果CefSharp编译的时候报错。遇到以下异常： libcef_dll_wrapper.lib(binary_value_ctocpp.obj) : error LNK2038: 检测到“RuntimeLibrary”的不匹配项: 值“MT_StaticRelease”不匹配值“MD_DynamicRelease”(ObjectsSerialization.obj 中) 原因： C++项目设置，运行库属性不匹配。 运行库属性，有四个选项及含义分别如下： 多线程调试Dll (/MDd) 对应的是MD_DynamicDebug 多线程Dll (/MD) 对应的是MD_DynamicRelease 多线程(/MT) 对应的是MD_StaticRelease 多线程(/MTd)对应的是MD_StaticDebug 详细文档见官网： /MD、/MT、/LD（使用运行时库） 解决方案： 在libcef_dll_wrapper.lib的项目属性中，修改为多线程调试Dll (/MDd) 来源： https://www.cnblogs.com/kybs0/p/11538290.html

CefSharp LoadHtml

问题 Could someone explain to me how the CefSharp LoadHtml function works? LoadHtml(string html, string url) What do the html and url parameters represent? I am interested in loading a page from a raw HTML string into the CefSharp browser. 回答1: Update: CefSharp has a new LoadHtml(string html) method that loads the HTML as a base64-encoded data URI. It is more reliable that the LoadHtml(string html, string url) method described below. In LoadHtml(string html, string url) : html is your HTML string,

CefSharp webpage element click

由 久未见 提交于 2019-11-29 15:51:18
I'm trying to do simple click on some page element(like a btn or link). I have wrote 2 functions for clicking via xpath and via CSS selectors. Both of those functions perfectly works in browser's developer console, but partially does'nt work in CEF. code perfectly click's in simple links from Developer Console and from Cef code perfectly click's on exact button from Developer Console but doesn't do click from CEF. It's just ignore it for some reason... How can this be? Js code is absolutely the same!... public void Click(string xpath) { var js = "document.evaluate(\"" + xpath + "\", document,

CEF Simulate Mousedown and Keysend

由 别说谁变了你拦得住时间么 提交于 2019-11-29 15:28:57
问题 I want to use CEF to control a Flash Application, so I need to simulate MouseDown and KeySend without JavaScript. I am using offscreen rendering. This is what I tried: managedCefBrowserAdapter.OnMouseButton( 500, 500, 0, true, 2, CefEventFlags.LeftMouseButton); or MouseEvent a = new MouseEvent(); a.Modifiers = CefEventFlags.LeftMouseButton; a.X = 500; a.Y = 500; or managedCefBrowserAdapter.SendKeyEvent(0, 0, 0); But nothing works. 回答1: This code works for me. Clicks once on the position 0, 0

CefSharp 3 set proxy at Runtime

由 纵饮孤独 提交于 2019-11-29 07:44:42
I downloaded CEF (chromuim embedded framework) binary distributation that comes with (cefclient & cefsimple) c++ examples, And Realized that cefclient can change proxy settings on run-time. And the key to do that is to Grab the RequestContext and call the function SetPreference. on CefClient all works just nice. but on CefSharp calling SetPreference always returns false, and also HasPreference returns false for the preference name "proxy". Aladdin thanks to amaitland the proper way to actively inforce changing the request-context prefrences, is to run the code on CEF UIThread as following: Cef
